Summary: The demand for rare earth elements (REEs) has been increased by contemporary industrial processes and the application of new technologies. However, the increased mining of REEs has led to a supply crisis. Researchers have recently started considering the viability of recovering REEs from secondary sources such as mining wastewaters and acid mine drainage. In order to find more sustainable processes, the performance of various adsorption/ion exchange materials in capturing REEs from water sources is being evaluated.

Summary: The hydration mechanism and multiple forces during the leaching process of ionic rare earth ore can cause fracture of the inter-particle bridge cementation and migration of microfine particles, leading to blockage and reduced leaching efficiency. This study investigated the effects of various factors on the migration of microfine particles and found it to be an important factor affecting leaching efficiency. Under the influence of external forces, the microfine particles tended to migrate with the leaching agent.

Summary: Developing the recovery technology of rhenium under high molybdenum background is of great importance in recycling rhenium resources from molybdenum concentrate leaching solution. A resin called LSL-N was synthesized with N-methylimidazole as the functional group, which showed a good adsorption capacity for Re(VII) and Mo(VI). The LSL-N resin can simultaneously enrich Re(VII) and Mo(VI) in the eluent, and both molybdenum and rhenium can be recovered through stepwise desorption with different desorbents.

Summary: This study investigated the adsorption characteristics of chitooligosaccharides on ion-exchange resin and found that the adsorption equilibrium followed the Langmuir model, with adsorption capacity decreasing with increasing degree of polymerization. The adsorption kinetics were well described by the pseudo-second-order kinetic model. Liquid-film diffusion and intra-particle diffusion were identified as the rate-limiting steps for adsorption. Thermodynamic analysis revealed that the adsorption of chitooligosaccharides on HX-7 resin was spontaneous and feasible, with higher polymerization degrees leading to stronger interaction forces and more favorable adsorption.

Summary: In this study, two dittmarite-type magnesium phosphates, KMP and NMP, were synthesized and demonstrated remarkable adsorption capacities for Cs+. However, their ability to adsorb Cs+ from environments with high divalent ion concentrations is limited. After adsorption, KMP and NMP were structurally transformed into CsMP, with two different stacking structures depending on the solution's pH. The high adsorption capacities of KMP and NMP can reduce the volume of radioactive waste for disposal.

Summary: Contamination caused by microbial fecal pollution in water bodies is a serious problem in many countries, especially in low- and middle-income countries. Fecal source tracking is an important method used to understand the source of fecal contamination and to decrease the hazard of waterborne diseases that occurs in the environment. The study used a human-associated genetic marker for Escherichia coli (H8) to investigate the source of fecal contamination in the Mae Klong River, Thailand, and the results showed a higher occurrence of E. coli with the H8 marker detection, indicating inadequate sewage treatment in the area.

Summary: This study further explores the application of the parametric group method of data handling (GMDH) in rainfall modeling and prediction using publicly available temperature and rainfall data. The ordinary GMDH approaches do not provide conclusive results due to lack of consistency in coefficients of determination and analysis of variance. Therefore, an empirical assessment is conducted to explain this inconsistency and improvements such as hybridization with least square support vector machines (LSSVM), application of filters for parameter estimation, and combination with signal processing techniques are investigated.

Summary: On-site wastewater treatment plants (OSTs) often lack monitoring, which makes their treatment performance unreliable. Low-maintenance but inaccurate soft sensors are emerging as a solution. We developed a stochastic model and found that soft sensors with 70% accuracy improved the treatment performance from 66% to 98%. Our study suggests using two soft sensors in practical settings: one optimized for maintenance scheduling and one optimized for performance quantification.

Summary: Researchers have developed a method that combines morphological and chemical information to accurately identify different particle types using optical measurement techniques that don't require sample preparation. By using a combined holographic imaging and Raman spectroscopy setup, they collected data from six different types of marine particles suspended in a large volume of seawater. Unsupervised feature learning was performed on the images and spectral data, and the learned features were combined to achieve better clustering results compared to using only image or spectral features. This method can be used for long-term monitoring of ocean particles without the need for sample collection, and it can be applied to different types of sensor measurements without significant modifications.

Summary: The construction of dams and other river infrastructures is threatening the population of migratory fish species by reducing river-floodplain connectivity. Fishways are important tools for restoring river connectivity for these fishes, but their effectiveness is often limited by a lack of biological information on the target species, especially in developing countries. This study aimed to inform the design of a vertical-slot fishway for migratory fishes in Myanmar. The results showed that the ability of fish to pass through the flume was influenced by hydraulic conditions and fish size. Obtaining baseline biological information on the target species is crucial for optimizing the effectiveness of planned fishways.

Handwashing technique affects the concentration of E. coli, with longer soap contact and cleaning between fingers being effective in reducing E. coli concentration. However, children's handwashing technique is not effective in completely eliminating E. coli from hands, and sustained and consistent handwashing practice is crucial for maximum effectiveness.

Summary: In this study, PVDF-based anion-exchange membranes were designed to selectively separate nitrate from chloride. Experimental data showed that increasing the concentration of PVDF enhanced nitrate transport but also increased the membrane electrical resistance. The selectivity of nitrate was found to be independent of the membrane thickness and mainly driven by the increased affinity between the anion and the membrane.

Summary: This study focuses on the modification of a commercially available polyamide thin-film composite membrane with a zwitterionic material to enhance its fouling resistance. The modified membrane shows improved salt rejection and reduced permeability compared to the pristine membrane. Fouling tests demonstrate that the modified membrane has a lower fouling ratio and higher recovery ratio. The enhanced antifouling characteristics are attributed to the improved hydrophilicity resulting from the zwitterionic brushes and the salting-in effect.
